Smile Out Loud

Harwell and Cook Orthodontics is Celebrating 50 Years of Smiles in Amarillo Texas Area and the Oklahoma Panhandle.

Harwell & Cook Orthodontics Top-Rated Orthodontics for Families in the Texas and Oklahoma Panhandles

Modern Braces and Clear Aligners

At Harwell & Cook Orthodontics, Dr. Anthony Harwell and Dr. Tanner Cook help kids, teens, and adults get healthier bites and straighter smiles. The practice is celebrating 50 years of smiles across Amarillo and the surrounding Panhandle communities. 

We offer proven options like Damon metal braces, clear ceramic braces, and Spark clear aligners, so you can pick what works best for your day-to-day life. Want “bright braces” energy? Teens can choose fun rubber band colors to match school spirit, sports teams, or just their favorite look. With advanced 3D imaging and custom planning, we focus on comfort, accuracy, and results you can feel proud of.

What Your First Visit Looks Like

Your first visit is simple: we listen, take the right scans, and explain your options in plain language. We use low-radiation 3D imaging (CBCT) to get a detailed view, which helps us plan treatment and avoid surprises later. No messy “goopy” impressions, your smile can be captured digitally and sent fast to our in-house lab for custom appliances. If you’re busy or live outside town, you can also start with a virtual consultation and move forward from there.

Meet The Orthodontists

Dr. Anthony Harwell & Dr. Tanner Cook

Dr. Anthony Harwell was raised in Amarillo and started learning orthodontics early by helping in his father’s practice. He studied at Vanderbilt, earned his dental degree at Baylor College of Dentistry, and completed orthodontic training at UT–Houston. Today, he carries on a patient-first approach that focuses on long-term results and a comfortable experience.

Dr. Tanner Cook grew up in Meers, Oklahoma, and earned his dental degree and orthodontic specialty training through the University of Oklahoma, completing his orthodontic residency in 2014. He’s passionate about helping teens build confidence and understands how to make treatment feel less stressful. He joined Harwell & Cook in 2014, and his goal is the same every day: clear answers, steady progress, and smiles patients love to show off.

Advanced Orthodontic Technology for More Comfortable Smiles

Great results start with better information, not more appointments. Our digital workflow helps us plan precisely, track progress, and keep treatment moving. From 3D imaging to in-house printing, we use tech that supports real-life schedules.

iCat (Airway Analysis)

We use the iCat FLX 3D Imaging System with CBCT to see your anatomy in high detail with low radiation. It also supports airway analysis, which can matter for issues like sleep apnea and growth.

iTero Digital Impressions

Instead of messy impressions, we use digital scans to capture your teeth and bite comfortably. The results are instant, so your treatment plan can move forward faster.

Dental Monitoring

With Dental Monitoring, you can send quick photos so we can check progress between visits. It’s a smart option for busy families and patients who travel in from smaller towns.

Technologically Advanced Brackets

We offer Damon braces, which are self-ligating brackets designed to use less pressure than traditional methods. Many patients like the comfortable feel and efficient tooth movement.

3D Printing Lab

Our in-house lab can 3D print items like clear aligners and retainers from your digital scan. Because it’s all digital, we can also save your scan for future replacement needs.

State-of-the-Art Braces Technology

Digital planning helps us build a cleaner roadmap for braces, aligners, and custom appliances. That means fewer surprises, better fit, and more confident decision-making from day one.
